One thing that's not in the guide is this: At last season's last event, there was a guy I spoke with who drove a mostly stock lancer... only thing he had done was RSB. He said that ever since installing it, he always spun out. Wasn't sure if it was the sway or his inexperience causing that, so he got a seasoned autoxer to drive the car on the course. but they spun out, too.
I can't recall if he'd changed any other suspension parts, but we basically came to the conclusion that his particular rsb was way too beefy and caused massive oversteer, so I advised he use the chalk method to gauge the point of underinflation and set his front tires just below that point. Helped a bunch for him, because the front underinflation promoted understeer which he could handle better than the snap-oversteer he was experiencing.
So the chalk method is also a sort of gauge to use for tuning your car's handling for a particular course sometimes outside the realm of simple tire traction.
